Function std.datetime.SysTime.fromISOExtString
Creates a SysTime from a string with the format
YYYY-MM-DDTHH:MM:SS.FFFFFFFTZ (where F is fractional seconds is the
time zone). Whitespace is stripped from the given string.
The exact format is exactly as described in
except that trailing zeroes are permitted - including having fractional
seconds with all zeroes. However, a decimal point with nothing following
it is invalid.
toISOExtString
If there is no time zone in the string, then LocalTime is used. If
the time zone is "Z", then is used. Otherwise, a
UTCSimpleTimeZone which corresponds to the given offset from UTC is
used. To get the returned SysTime to be a particular time
zone, pass in that time zone and the SysTime to be returned
will be converted to that time zone (though it will still be read in as
whatever time zone is in its string).
The accepted formats for time zone offsets are +H, -H, +HH, -HH, +H:MM, -H:MM, +HH:MM, and -HH:MM.
Prototype
SysTime fromISOExtString(S)( S isoExtString, TimeZone tz = null ) @safe if (isSomeString!S);
Parameters
| Name | Description |
|---|---|
| isoExtString | A string formatted in the ISO Extended format for dates and times. |
| tz | The time zone to convert the given time to (no conversion occurs if null). |
Throws
DateTimeException if the given string is not in the ISO format
or if the resulting SysTime would not be valid.
Example
assert(SysTime.fromISOExtString("2010-07-04T07:06:12") ==
SysTime(DateTime(2010, 7, 4, 7, 6, 12)));
assert(SysTime.fromISOExtString("1998-12-25T02:15:00.007") ==
SysTime(DateTime(1998, 12, 25, 2, 15, 0), msecs(7)));
assert(SysTime.fromISOExtString("0000-01-05T23:09:59.00002") ==
SysTime(DateTime(0, 1, 5, 23, 9, 59), usecs(20)));
assert(SysTime.fromISOExtString("-0004-01-05T00:00:02") ==
SysTime(DateTime(-4, 1, 5, 0, 0, 2)));
assert(SysTime.fromISOExtString(" 2010-07-04T07:06:12 ") ==
SysTime(DateTime(2010, 7, 4, 7, 6, 12)));
assert(SysTime.fromISOExtString("2010-07-04T07:06:12Z") ==
SysTime(DateTime(2010, 7, 4, 7, 6, 12), UTC()));
assert(SysTime.fromISOExtString("2010-07-04T07:06:12-8:00") ==
SysTime(DateTime(2010, 7, 4, 7, 6, 12),
new immutable SimpleTimeZone(dur!"hours"(-8))));
assert(SysTime.fromISOExtString("2010-07-04T07:06:12+8:00") ==
SysTime(DateTime(2010, 7, 4, 7, 6, 12),
new immutable SimpleTimeZone(dur!"hours"(8))));
